Non-MLB
Although they have not thrown an MLB pitch in 2024, Luis Vizcaino threw 1,376 pitches that were tracked by the PITCHf/x system between 2007 and 2009, all of them occuring in the MLB Regular Season. In 2009, they relied primarily on their Slider (83mph) and Fourseam Fastball (92mph), also mixing in a Splitter (88mph).
In 2009, compared to other RHP:
Their slider is basically never swung at and missed compared to other pitchers' sliders and results in more flyballs compared to other pitchers' sliders. Their fourseam fastball has some natural sinking action, has essentially average velo and has slight armside run. Their splitter (take this with a grain of salt because they've only thrown 19 of them in 2009) is basically never swung at and missed compared to other pitchers' splitters, is much firmer than usual, has movement that suggests a lot of backspin, results in somewhat more flyballs compared to other pitchers' splitters and has slight armside fade.
